electrical

I have a 1988 Ford f150 Lariat. I have repleced the battery, the starter, the alternater. Now the only way I can get it to start is to hook jumpercable to another battery and the ground cable to anything but the gound post. I have run out of ideas. Help.

Sounds like you have a bad ground cable to start with. Plus the possibility of something else drawing the battery down. The cable may look fine, but has broken down to the poin inside that it will not carry sufficient current. I have experienced this personally as well as seen it in customer cars.
Hope this is helpful to ya,

bde33 do you have a digital voltmeter?If so you can test the cables very easily.I would suggest both cables be replaced with quality fat thick cables not skinny cheap chain store cables if you end up needing them.
